HUGH E. HALE AND JOHN O. POTTS, OF ST. LOUIS, MISSOURI.

HAND-CAR.

To all whom it may concern:

Be it known that we, HUGH E. HALE and J OI-IN O. POTTS, citizens of theUnited States, and residents of the city of St. Louis, in the State ofMissouri, have jointly invented certain Improvements in Hand-Cars, ofwhich the following is a specification.

Our invention is a hand car having improved means for holding in meshthe gears through which the axle is driven, so that the car can beoperated notwithstanding the bending or disarrangement of the axle.

In the preferred form of our construction, the axle is journaled in asteady box, which is placed near the driven pinion fixed on the axle,and the steady box is connected by a reach rod with a pivotal supportcarried by a bearing which is fixed to the car frame, so that the reachrod is adapted to turn about an axis disposed in or near the planecontaining the axis of the pinion and of the driving gear engagingtherewith.

In the accompanying drawings, Figure 1 represents a sectional plan viewof a hand car having our improvement-s applied thereto; Fig. 2 is asectional side elevation of the same; and Fig. 3 is a sectional sideelevation showing in enlarged view our improved means connecting a caraxle and sill.

Our improvements, as shown in the drawings, are applied to a usual typeof car, com prising the wheels 1 fixed on the axles 2, the frame 3carried by the axles, the bent 1 carried by the frame, the hand lever 5having the crank arm 6, the journal bearing 7 whereby the lever isfulcrumed on the bent, the rod 9 having the pivotal connection 8 withthe arm 6 by which it is operated, the driving gear 11 having the axle12 whereby it is journaled in the frame, the crank pin connection 10between the rod and the gear 11 whereby the latter is revolved, and thedriven gear or pinion 13 fixed on an axle 2 and meshing with the gear 11which revolves it.

The axle 2, which carries the pinion l3, revolves in a steady box orbearing 14 which is composed of the member 15 connected with the reachrod 16 and the member 17 connected adjustably with the member 15 bybolts 18. The reach rod extends to and is pivotally supported by anarbor or pivot 19 carried by a shoe or bracket 20 which is fixed to apart of the car frame, as the sill 21, so that the pivot 19 lies betweenthe axes of the Specification of Letters Patent.

gears 11 and 13, in or near the plane passing through such axes. In thisconstruction, the reach rod 16, thus connecting the driven axle 2 withthe car sill 21 through the steady box 14 and the bracket 20, will holdthis axle, which carries the driven pinion 13, so that it is limited toa movement from its normal position around the periphery of the drivinggear 11 and consequently in such movement of the axle the driven plnionwill remain in mesh with the driving gear and maintain its properoperating relation therewith.

Having described our invention, we claim: 1. In a hand car, a revolubleaxle, a pinion fixed thereon and a driving gear in mesh with saidpinion, in combination with a reach rod having a bearing in which saidaxle revolves and a support about which said bearing is adapted to turn,for the purpose specified.

2. In a hand car, an axle, a pinion fixed thereon and a driving gearengaging said pinion, in combination with a reach rod having a bearingin which said axle is journaled and a pivotal connection disposedbetween the axes of said pinion and gear.

3. In a hand car, a frame, an axle journaled relatively thereto, apinion fixed on said axle, a driving gear journaled relatively to saidframe and engaging with said pinion, a reach rod having a bearing inwhich said axle is journaled, and means fixed to said frame with whichsaid rod is pivotally connected so that said pinion is held againstsubstantial movement away from said gear.

4. In a hand car, a frame, an axle journaled relatively thereto, apinion fixed on said axle, a driving gear journaled relatively to saidframe and engaging with said pinion, a reach rod having a bearing inwhich said axle is journaled, and means fixedto said frame with whichsaid rod is pivotally connected so that said pinion is held againstsubstantial movement away from said gear and allowed to movecircumferentially thereto.

In witness whereof we have hereunto set our names this 5th day ofAugust, 1909, in the presence of the subscribing witnesses.
